Harm (Harmen) Schoemaker (Schoenmaker), a Dutch Anabaptist, who by his unsound bigoted fanaticism (he called himself the Messiah and even God the Father) caused a tumult at 't Zandt, Dutch province of Groningen, in January 1535. On the farm called "De Arke," owned by Eppe Pietersz, a wealthy farmer, a large crowd gathered, over 300 of whom were baptized in one night by Schoenmaker, assisted by Cornelis int Kershof. Schoenmaker was arrested and put in prison in Groningen, where he soon died insane. He clearly took the Münsterite views and initially considered himself an elect to bear the banner of God from Groningen to Münster; i.e., to be the leader of the revolutionary Anabaptists of the Groningen region to the New Zion, which Jan van Leiden had erected in Münster.
